Hello Bas,
Once the purchase is made, we will work with you or your IT group to help get the software loaded onto your computer and we will have your database on the Enterprise edition. Since we have your data, we will do the data conversion into the new version. As far as your second question, you will be assigned an implementation specialist that will work with you from beginning to end. We will need to work different hours on our end, but we have done this before. The implementation is getting pretty booked, especially for yearend so the sooner we can move forward the sooner we can plan your training.
Please let me know if you have any questions.
Thanks,
